So I let my gf drive the car for a while since we were in the middle of fixing her S4. Any who.... now when you turn it on it idles like crap but if you rev it once or twice it idles just fine?. Than when you drive it, it feels like it's attempting to boost but the power is definitely not there. I got the codes P1188, P1189, P0306 I also had another code if I remember correctly before I cleared it that had to do with the o2 sensor. What's your guys thoughts?
